In Israel, more than 12,400 people have tested positive for coronavirus after being vaccinated with the Pfizer/BioNTech jab, including 69 who had received their second dose, the country’s Health Ministry said.

189,000 people were tested for Covid-19 after being vaccinated, with 6.6 per cent tested positive, according to ministry data reported by Israeli outlets. The majority were infected shortly after receiving the first jab of the two-part vaccine – a period when the inoculation isn’t expected to have kicked in yet.

14 days after the first injection 1,410 people tested positive by which time partial immunity should have already taken effect.

In addition, 69 patients became infected with the coronavirus despite already having been administered both shots of the vaccine, the ministry said. Israel began administering the second doses almost two weeks ago, with Prime Minister Benjamin Netanyahu being the first to complete the course.

According to the manufacturer of the jab, Pfizer has said that a spike in immunity occurs between Day 15 and Day 21 after the first jab, when the effectiveness of its vaccine increases from 52 to 89 percent. According to earlier trials, the protection offered by the vaccine reaches the 95 percent level a week after the second dose is administered, the pharma giant said.

When it comes to vaccines, the results of clinical trials may differ from how the immunization performs in the field, where it’s administered to a much greater number of people.

On Tuesday, Israel’s coronavirus tsar, Nachman Ash, reportedly complained to Israeli ministers about the insufficient protection provided by the first shot of the American vaccine. It turned out to be “less effective than we had thought” and “lower than Pfizer presented,” Ash said, as cited by Army Radio.

According to Professor Gili Regev-Yohai, 102 of the medics at the center were tested a week after completing the vaccination course, and all but two of them showed antibody levels between six to 20 times higher than seven days earlier.

A WHO representative for Palestine said that the UN body has been in discussions with Israeli authorities on the possibility of allocating vaccines to the Gaza Strip and West Bank. Israeli Health Minister, Yuli Edelstein, has said her department may offer the Palestinian Authoritiy surplus doses after Israelis have received their jabs.
